##Follow the procedure:
Before running the project please install PostgreSQL 10 or above.
If you're a Windows 10 user there might be an issue with encoding check if it's relative to you the troubleshooting might be to open a config file:
C:\Program Files\PostgreSQL\VERSION\data\postgresql.conf
changing the lc_messages value of Russian_Ukraine.1251 to en_EN. utf-8
Next, open a Windows Environment variables and add the following line to PATH
C:\Program Files\PostgreSQL\YOUR_CURRENT_VERSION\bin
Change values in METHOD column to trust provided you're under development mode
C:/Program Files/PostgreSQL/YOUR_CURRENT_VERSION/data/pg_hba.conf
Run psql and reload your config. Alternatively if you're a Windows user go to a control panel, open services and restart a postgresql service itself
select pg_reload_conf();
Use "postgres" username to enter to a postgresql CLI once you run psql and then your password would be the password you specified during PostgreSQL installation. If you're going to create your own account, type the command:
create role USERNAME login superuser;
Mind! All commands should be closed with semicolon! Enter the line to create a new password for your just created account:
\password USERNAME;
You won't be able to use your account if you haven't created a new database:
create database USERNAME;
The PostgreSQL command to list existing databases
\l
Open Terminal and then go to server directly. Initialize a project database
npm run initdb
